GAS-ENGINE.

SPECIFICATION forming part of Letters'Patent No. 272,130, datedFebruary13V, 1883.

Application tiled August 9, 1881. i (Model.) Patented in France May 16,1881,

England July 16, 1881, No. 3,113,- in Italy July 23, 1881,

To all whom it may concern: l

Be it known that we, EUGNE ETVE and CHARLES CLMENT LALLEMENT, mechanicalengineers, of Paris, in the Republic of France, have invented YanIinprovementin GasEn eines, (for which we have obtained Letters* Patentot France for iifteen years, dated May 16, 1881, No. 142,877;) and We dohereby description thereof, reference being made to the accompanyingdrawings.

It is a known fact that gas-motors have the advantage that they dispensewith fireplaces, with special attendance and wa-tchi'ulness, and thattheyconsume fuel only when in actual use.' They are, however,inconvenient in requiring special and costly apparatuses for geution hasbeen restricted almostentirely to large cities or towns.

Attempts have heretofore been made to burn hydrocarburets; but it wasfound that the feeding of the machines was at least as expenwere unsafeand liable to explode.

rlhe new motive-power engine which forms the object of our inventionoffers all the advantages of those Worked by gas, without theirinconveniences, or those using hydrocarburets. It is of a simple andeconomical construction, very similar to that ot' a steam-engine.` Itproed for operating it, and consequently cuts off its consumption assoon as'it stops.

The production of the hydrocarbureted liuid consists in `injecting astream of compressed air into a recipient which contains any kind ofhydrocarburets`such as petroleum, for instance, or any other equivalentmaterial-and to mix this hydrocarburet with the compressed air withinthe cylinder, so that the mixture will be in the space adjoining thepiston. An electrical spark causes the ignition of the contents, and itsimmediate expansion moves the piston, the power being still increased byin creasing the pressure of the air admitted. The quantity ofhydrocarburet in each cylinder is very small-only enough to render themixture inammable. The generator occupies but a small space and maybeeasily removed from one place to another. All carea'nd watchful- No.142,877; in Belgium May 18, 1881, No. 54,668,- in

ness may be dispensed with, as all its doings are automatic, so that themost-inexperienced hand may set it to work or stop it, as desired. Themore the resistance increases the longer will the'inlet-ports for thehydrocarbureted air remain open, and consequently the combustion and thepower of the'uiixture thus introduced will augment in the sameproportion.

The drawings forming part of this specication are intended merely todemonstrate the application ot' the system of our new motor, and it isobvious that the general arrangements, as well as the new organs of thisengine, may undergo such changes in form and construction as engines areusually subjected to.

Figure l is a side elevation. Fig. 2 is atop view partly in section.Fig. 3 is a vertical section across the cylinder.

The cylinder ais secured upon the bed b, which stands 4on legs b. Thecrank-shaft c, which rests in bearings that may be cast on the bedorjoined to it, is connected to the cross head p of the piston-rod p,which moves in guides e e. A iiy-'wheeh o, is'keyed on said shaft. Thecrank-shaft c, or the head of the connecting-rod, connects by suitablelinks or levers,lff2f3, with the piston ot' a suitable aircompressor,f4, of ordinary construction. The compressed air of the air compressorf4, by means ot' tube f5, is let to the generator g ot' hyuirocarburetedair, into which is poured either petroleum or any other equivalent hydrocarburets, and into which enter two tubes, the one, lc, leading tothe upper, and the other, l, leading to the lower part oi' vessel g.rIhe pipe k is above the recipient g, divided into branches m m', (seeFig. 2,) that' end in the collector of the slide-valve t or distributor.The tube Z is in like manner divided into two branches, n a', that enterthe same collector. The slide-valve t moves between two glass plates, 'iand j, the latter being fixed to the cylinder, close to its apertures rr', one ot'which is intended for the air and the other for thepetroleum. The rod t2 of the slide-valve is conducted by one or twoeccentrics of shaft c. The escapement is regulated by a secondslidevalve, s, which is commanded by the eccen`- `tric s' on shaft c.

It remains to be explained how 4the engine ICO edges with two contactsnearly opposite each other. yyz, the one for theforward an d the otherfor the backward movements. These contacts are intended for pressingupon a commutator, A, with which one of the wires, F, is united, theother wire, F', ot' the magnet being in direct relation with aninduction bobbin, B.

' This bobbin through wire sends back the iuid into'the bed b, and by a.second wire into another commutator, C, Fig. 2, which corresponds with asmall disk, o, on shaft c. The disk ois made of hardened or vulcanizedrubber, in which is enrolled a copper wire with two contacts, one forthe forward and the other for the backward movement. Two wires, F3 F4,extend from the contacts of this disk o to the cylinders heads at thepoints G. The electro magnet might be replaced by a pile, but theinduction-bobbin will distribute the electrical fluid all the same.

Functions of tzc-cttgi1ze.-For the starting it is necessary to impart tothe fly-wheel sev'- eral rotations for the purpose ot' generating asmall quantity of air under pressure. A stopcock on the pipe 7c actsupon the compressor 3o f4 and causes the generation to be without theaid ofthe hydrocarburet. It' we suppose that the piston is shownbackward, then the slidevalve will show the corresponding openings, rr', so as to admit into the cylinder a. air under pressure andpetroleum; but as a. consequence of the pressure ot' the air itself, andeven of the aspiration by the piston, the hydrocarburet projects itselt'and pulverizes within the cylinder, and instantaneously and impalpablythe Huid is mixing with the air. When arrived at the two-t'ths of thestroke of the piston the slide-valve shuts the openings, and .instantlyone ot' the contacts of the pulley y presses upon the commutator A,which leads the magnetic tluid into the inductionbobbin, and at the sametime the other commutator, C, generates the spark within the cylinder.The ignited gases expand and violently atentany push the piston aheadduring the remaining' three-fths ofthe stroke. When the piston "makesits back motion the slide-valves opens the recess ot' the rear-f0r thepurpose ot' exhausting the burned gases, while thedistribution isaccomplished at the opposite face of the piston in the same way by thereversed working of the valvc't. After a few rotations the engine isstarted and does not require any l more care or watching. aliceincreases the speed of the piston diminishes, and the inlet-ports remainopen for a greater length'ot' time, so as to admit-a larger quantityofhydrocarburet and air, which causes a more powerful effect from everypiston-stroke. After a few rotations the engine regulates its movementaccording to the resistance and worksregularly. The pressure ot'the air,which is to be admitted into the recipient ot' the hydrocarbnret, mightbe regulated so as to admit at any time such quantity ot' hydrocarburetas is desired to do the work at the time.

We claiml. The combination of the cylinder et and its piston with theshaft. c, air-compressing apparatus,f4, means, substantially asdescribed, for operating said air-compressing apparatus, connection f5,mixing-chamber g, pipes 7i: and Z, slide-valve t, and spark-generatingapparatus B C 0,'all arranged substantially as herein shown anddescribed.

2. The combination ofthe cylinder t wit Athe magnet x, pulleys m and y,shaft c, com- Nalves,s and t, and with the inletpipes m,m,

n, and fn', and electric conductors F3 and F4, substantially as hereinshown and described.
